The Falls Incline Railway at Niagara Falls has an angle of elevation of 36º. The railway extends a horizontal distance of about 138 feet. Find the height and length of the railway.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

28

step-by-step explanation:

because that's the answer

d.) yes, because the volume of the cone is greater than the volume of the sphere
